You are absolutely correct. For a single GTX 680, nVidia recommends a minimum 550W PSU with at least (2) 6-pin PCIe power connectors. In general, get a PSU from a good mfr, a short list of quality mfrs: Antec, Corsair, Seasonic, XFX, Enermax

Great little PSU from Rosewill is the Capstone 550W: http://www.newegg.com/Product/Product.aspx?Item=N82E168... Although it's not on my short list, this is a great PSU made by a quality OEM for Rosewill. Review of the 750W version: http://www.jonnyguru.com/modules.php?name=NDReviews&op=...
I personally love my Seasonic M12II-520W: http://www.newegg.com/Product/Product.aspx?Item=N82E168... Modular, 5 yr warranty 40A on the 12V rail...enough for your rig.

My friend said for a 650w PSU but i think that that will be too little seeing as the i5 will use 95 watts which will bring it up to 645w, that doesn't leave enough space imo so do you think i should get a 750w instead?

Go for a Corsair TX650. Going for $90 on Amazon.

Also, the Seasonic listed above is great. Highly recommended.

EDIT:
OP you got it wrong. The 550W recommendation is including the CPU and whatnot. The actual consumption by the card alone is just around 200W. The remaining 350W is the headroom for the CPU, storage etc.

The 550W PSU recommendation from nvidia is for the entire system. The max power draw for the GTX680 is 195W, your GPU is 95W, the rest of your system is maybe another 75-100W; your actual power usage is likely to be lower even when gaming. A good quality 550W PSU is enough to power your rig. Take a look at this article on power consumption in modern PCs: http://www.silentpcreview.com/Power_Distribution_in_Thr...

sorry for my mistake, do you think the C/Master Extreme 650W will be good enough?

Before something dangerous or unnecessary happens, The power on the 12v rail(s) is more important than the total wattage of the PSU for a gaming rig.

Find the individual rail ratings (will look like 12v@20a). multiplying the amps by the voltage will give you the watts of the rail. Compare that to the power the video card draws under load.

Having said that, a 750 watt PSU with proper power on it's 12v rails would be enough for two 680's.

From that list, the PSUs that I would trust and that meet your requirements are the Antec Neo Eco 620W, the Antec Eartwatts 650W, and the Antec HCG 620W.

For get Calculators, select a review for the GPU. Most reviews will list what the System power is, then add 25% and Get a "quality" PSU.

My System, I5-2500k OCed to 4.2 w/ ATI 6870 GPU, 16 Gigs Ram, 2 SSDs, one HDD, One blue ray writer. = 350 Watts at the Wall and that is very close to what most reviews of the 650 show.

If NOT planning on a 2nd GPU, 650W or UNDER, if SLI/Xfire 650 ->750 Watt.

How is it the Corsair GS-600 not making any lists so far? Thats a great PSU at $95

http://cpl.net.au/online-shop?page=shop.product_details...

Thats where I would go.

The previously suggested Antec units are also wonderful units for the price. But If I had to choose from that list at under $100, I would choose the Corsair GS-600.
